[Security] Bump highlight.js from 9.12.0 to 10.1.2

[dependabot-preview[bot]]

Bumps highlight.js from 9.12.0 to 10.1.2. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Prototype Pollution in highlight.js

Impact

Affected versions of this package are vulnerable to Prototype Pollution. A malicious HTML code block can be crafted that will result in prototype pollution of the base object's prototype during highlighting. If you allow users to insert custom HTML code blocks into your page/app via parsing Markdown code blocks (or similar) and do not filter the language names the user can provide you may be vulnerable.

The pollution should just be harmless data but this can cause problems for applications not expecting these properties to exist and can result in strange behavior or application crashes, i.e. a potential DOS vector.

If your website or application does not render user provided data it should be unaffected.

Patches

Versions 9.18.2 and 10.1.2 and newer include fixes for this vulnerability. If you are using version 7 or 8 you are encouraged to upgrade to a newer release.

Workarounds

Patch your library

Manually patch your library to create null objects for both languages and aliases:

const HLJS = function(hljs) {
</tr></table> ... (truncated)
Affected versions: < 9.18.2

Release notes

Sourced from highlight.js's releases.

10.1.2

Fixes:

• fix(night) Prevent object prototype values from being returned by getLanguage (#2636) night

10.1.1

Fixes:

• Resolve issue on Node 6 due to dangling comma (#2608) [Edwin Hoogerbeets][]
• Resolve index.d.ts is not a module error (#2603) [Josh Goebel][]

10.1.0

Just your typical minor release. Plenty of fixes and enhancements, few new themes.

Some deprecations language maintainers might want to pay attention to:

• htmlbars grammar is now deprecated. Use handlebars instead. (#2344) [Nils Knappmeier][]
• when using highlightBlock result.re deprecated. Use result.relevance instead. (#2552) [Josh Goebel][]
• ditto for result.second_best.re => result.second_best.relevance (#2552)
• lexemes is now deprecated in favor of keywords.$pattern key (#2519) [Josh Goebel][]
• endSameAsBegin is now deprecated. (#2261) [Josh Goebel][]

10.0.2

Fixes a serious potential freeze/infinite loop issue. Everyone on version 10 should upgrade.

• Remove support for AMD module loading, which never truly worked properly anyways.

10.0.1

Fixes: sublanguage with no rule matches causes text to disappear in final output. (#2506).

10.0.0

Welcome to version 10.0. This a major release and therefore will contain breaking changes.

Breaking Changes

Our normal minor releases try to never break anything, holding all breaking changes for major releases. We tried to squeeze in as many as we could this time so that after 10.0 ships we'll be back to quiet sailing for a while before we need to push version 11. That said, we're very conservative about what we consider a breaking change.

i.e., if there it could possibly break things for anyone, it's typically a breaking change. The fact is a vast majority of users should upgrade and probably not notice any changes at all.

See VERSION_10_BREAKING_CHANGES.md for a comprehensive list of breaking changes, but here is a summary... if you use:

Core highlight.js lib on the client (with no extra CDN languages)

Just keep doing that.

• If you're using darkula.css, you'll need to change that to darcula.css
